Deceleration starts at the front end of the proximity dog. After
the rear end is passed, the position specified by the first Z-
phase signal, or the position of the first Z-phase signal shifted
by the specified home position shift distance is used as the
home position.
In the indexer method, deceleration starts at the front end of the
proximity dog, and then the first Z-phase signal at which a
deceleration to a stop is possible or the position of the Z-phase
signal shifted by the specified home position shift distance is
used as the home position. The torque limit values in Positive
torque limit value (60E0h) and Negative torque limit value
(60E1h) are enabled during execution of home position return,
and the torque limit value in Torque limit value2 (2D6Bh) is
enabled when the home position return is stopped.
At the front end of the proximity dog, deceleration starts. After
the front end is passed, the position specified by the first Z-
phase signal after the set distance or the position of the Z-
phase signal shifted by the set home position shift distance is
set as a home position. If the stroke end is detected during
home position return, the travel direction is reversed.
The current position is set as the home position.
In the indexer method, the current position is set as the home
position. The torque limit value becomes 0 when switched to
the homing mode (hm).
A workpiece is pressed against a mechanical stopper, and the
position where it is stopped is set as the home position. If the
stroke end is detected during home position return, [AL. 90
Home position return incomplete warning] occurs.
The position where the servo is switched on is used as the
home position.
Deceleration starts from the front end of the proximity dog. After
the rear end is passed, the position is shifted by the travel
distance after proximity dog and the home position shift
distance. The position after the shifts is set as the home
position. If the stroke end is detected during home position
return, the travel direction is reversed.
Deceleration starts from the front end of the proximity dog. The
position is shifted by the travel distance after proximity dog and
the home position shift distance. The position after the shifts is
set as the home position. If the stroke end is detected during
home position return, the travel direction is reversed.
A position, which is specified by the first Z-phase signal after
the front end of the proximity dog is detected, is set as the
home position. If the stroke end is detected during home
position return, the travel direction is reversed.
After the front end of the proximity dog is detected, the position
is shifted away from the proximity dog in the reverse direction.
Then, the position specified by the first Z-phase signal or the
position of the first Z-phase signal shifted by the home position
shift distance is used as the home position. If the stroke end is
detected during home position return, the travel direction is
reversed.
Starting from the front end of the proximity dog, the position is
shifted by the travel distance after proximity dog and the home
position shift distance. The position after the shifts is set as the
home position. If the stroke end is detected during home
position return, the travel direction is reversed.
The position specified by the first Z-phase signal, or the
position of the first Z-phase signal shifted by the home position
shift distance is used as the home position. If the stroke end is
detected during home position return, [AL. 90 Home position
return incomplete warning] occurs.
